The figure shows a and b as adjacent angles. To find pairs of adjacent angles, simply look for two angles that share a node and a side, and the two angles will be the same. Definitions and examples of adjacent angles | Definitions of adjacent angles - Geometry

Contiguous" means "next" or "neighboring" angles are angles that are directly adjacent to each other. Adjoining angles divide a shared apex and a shared side, but do not overlay. When two adjacent angles make a right corner (180o), they are complementary. Shown in the illustration are a and a adjacent angles.

You have a shared node M and a shared page OA. Rename all adjacent angle couples in the graph. Adjoining angles are angles that lie directly next to each other. Adjoining angles divide a shared apex and a shared side, but do not overlay. Corresponding to the above picture, a and b, e and a are the couples of the neighboring angel in the figure above.

## Adjoining Angles - Problem 1

Adjoining angles are angles that have a shared apex and a shared side. So to find a pair of adjacent angles, just look for two angles that divide a knot and a side. This example shows that ?FAE and ?EAD have both nodes A and side AE so that they are next to each other.

Both contain the node A and the side BA, so that they lie next to each other. In order to show you some examples of what I mean by neighboring angles. We are going to deal with a situation where you have to find two couples of adjacent angles. Well, if I begin by looking at an FAE angular, then I will look at that angular right there, FAE angular.

You have two options for an adjacent corner, here is our apex and it has two different sides, so we can use the EAD one. So, I'd like to say that these two angles are side by side. Or I could have used the FAB bracket. Let's assume FAE and EAD are adjacent angles.

Let's choose another corner, let's say we have used BAC angles, note that I used the same number of markers here because they have to be the same. This is a couple of perpendicular angles. Thus BAC, so BAC angles and another adjacent BAC could be this large blunt BAF angles. And so I will be writing the BAF corner.

Adjoining angles divide a shared apex and a shared side.
